Combining UWB Real-Time Locating System with secure transporter authentication

 

In many business and industrial processes, objects such as containers, components, machines and finished packaged goods must be securely transported by authorized persons or robots from location A to location B.

Ensuring that this process is successfully executed at the right time, at the right place, along the right route, and by the right person or robot is crucial. It is also important to automatically log all movements for quality, reporting, security and auditing purposes.

As many of these processes are carried out in GPS denied areas (indoors), the ZIGPOS RTLS can be implemented using “Ultra-Wideband” (UWB) technology. The wide-bandwidth of UWB means that the signal transit times can be accurately measured as well as easily pass through walls and obstacles and operate in the presence of other radio signals, such as those from mobile phones, WLAN and Bluetooth transmitters.

Based on robust 500+ MHz UWB radio signals, Dresden-based ZIGPOS has developed an indoor locating system that localizes people and objects in 3 dimensions to within 30 cm. Objects are fitted with a UWB transmitter that is tracked by at least 3 receivers which enables calculation of location based on trilateration*. Object identifier and timestamp are also recorded.

To securely verify that only an authorized person or machine is handling the object, the LEGIC Security Platform has been integrated into the system. The design includes LEGIC’s EAL 5+ certified IoT security module SM-6310 embedded in each ZIGPOS RTLS-enabled object. The contactless modules verify a transporter’s credentials which are stored on the transporters’ RFID tag, smartcard or smartphone. 

Credentials are managed and distributed via LEGIC’s cloud-based Security Platform. Leveraging “Root-of-Trust” for secure management of people interacting with things, the RTLS turns object data and spatial context into secure, actionable information.

    Guiding objects to the right destination

    When an object needs to be moved, for example, the transporter’s RTLS transponder tag or smartcard is verified via “Near-Field Communications” (NFC) by the RTLS-enabled object. LEGIC’s technology enables instant authentication of the transporter, either human or robot, and passes its credentials to the RTLS application. The application authenticates the transporter and communicates to the transporter via an ePaper display the details about when and to what destination the object should be moved, and along which route. Once the object detects movement, a visual and/or audio indicator (green/red light and alarm) confirms whether the correct person or machine is transporting the object.

    LEGIC’s Security Platform enables the secure cloud-management of users and credentials via contactless smartcard. This gives the ability to authenticate, track and guide people and robots and their payload to the correct destination.

    Features of the ZIGPOS UWB RTLS:

    • Secure Auto-Identification of human or machine transporters based on the LEGIC Security Platform
    • End-to-end (E2E) tracking of goods via RTLS and GPS/GNSS
    • Real-time indoor positioning and tracking to within 30 cm
    • Micro-navigation to help transporters reach their destination
    • Key management and access control to enclosed rooms
    • Geofencing - Detection of when objects enter or leave designated areas
